The Met Office warns that temperatures are expected to exceed 30C in many areas and it's likely to stay warm and very humid overnight. While Wednesday (August 8) is forecast to be cooler, temperatures could still reach the mid to upper 20s.

Older people, the very young and those with ongoing illnesses are expected to feel the effects of the ongoing heatwave more acutely.

Val Thomas, Consultant in Public Health at Cambridgeshire County Council, said: “While hot weather is enjoyable for most people, for some it is challenging. High temperatures can be very uncomfortable and affect the health of the young and older people.

"It can also worsen the condition of those with an ongoing health condition, especially for those with heart and lung problems.

"As the heatwave continues, we're asking people to look out for those at risk from high temperatures –to make sure they are able to keep cool."
